So these runes are clearly exceedingly rare and can provide a monumental advantage offensively by allowing some abilities to be used a round earlier. Assuming these energy runes stack with each other, it seems unlikely DB will ever make two of the same element rune available lest an attacker gets +2 energy. If this is the case, what is the stance towards players who do not have these energy runes, and how would one be able to obtain them?
I don't agree with the 'you snooze you lose so you'll never get it' argument because the advantage you can get is too great to just brush off (namely Shade Spirit linking t1). I missed the dark community energy rune because I was on a hiatus when it was released, which is fine, but seemingly never being able to get that rune due to aforementioned logic puts a bad taste in my mouth.
To be clear, I'm not saying I deserve a rune I missed for not being on at the time. All unique runes should be unique to the people who are able to obtain them. But something like Burning Skin or +10% hp every round is incomparable to +1 energy, which is such a huge advantage that never being able to get it puts someone who does have it far ahead of someone who doesn't, regardless of setup. I'd like to see at least an opportunity for those who missed out to be able to recoup their losses, even if that chance is just once a year.
